Abstract
Canopy is lifted the utility model discloses a kind of fully-mechanized mining working automatic moving type, including at least two groups lift canopy supports being connected with each other by push cylinder, the lift canopy support includes back timber, bottom girder, footstock, base and telescopic column, the footstock is set on back timber, the base is arranged on bottom girder, the telescopic column two ends connect footstock and base by bearing pin respectively, and the push cylinder two ends connect the base of two groups of lift canopy supports respectively.The spacing that the utility model passes through the freely adjustable two groups of lifts canopy support of push cylinder, pass through the height of the freely adjustable lift canopy support of telescopic column, it is simple in construction, operation is flexible, overcome traditional advance support and there are problems that process efficiency is low, labor strength is big, dangerous, back of constructing sinks, and fast, termination is difficult, it is adaptable to generic fully-mechanized mining working.
Description
Technical field
The utility model is related to coal mine machinery field, more particularly to a kind of fully-mechanized mining working automatic moving type lift canopy.
Background technology
(i.e. termination) place control top area is exported above and below fully-mechanized mining working big, exploited in working face across pitch and along inclined plane
Supporting pressure superposition at, surrouding rock deformation acutely, the replacement of advance timbering in addition, make advanced section back crush, be top plate
Black spot.And equipment is concentrated herein, the traffic main artery that material and personnel come in and go out is into and out again, if face end
Generation accident, then pause the production for causing whole working face, thus face end and up and down advanced section strengthening supporting show
Obtain particularly important.And traditional advance support is present that process efficiency is low, labor strength big, dangerous, back of constructing
The problems such as sinking is fast, termination is difficult supporting.
Utility model content
In order to solve the above technical problems, canopy is lifted the utility model discloses a kind of fully-mechanized mining working automatic moving type, including at least
Two groups of lift canopy supports for being connected with each other by push cylinder, the lift canopy support includes back timber, bottom girder, footstock, base and stretched
Contracting column, the footstock is set on back timber, and the base is arranged on bottom girder, and the telescopic column two ends are connected by bearing pin respectively
Footstock and base are connect, the push cylinder two ends connect the base of two groups of lift canopy supports respectively.
As the further improvement of above-mentioned technical proposal, the back timber is the I-steel of 2600mm length.
As the further improvement of above-mentioned technical proposal, the bottom girder is the I-steel of 2240mm length.
As the further improvement of above-mentioned technical proposal, the telescopic column is stroke 840mm ZF2200/16/24
Type hydraulically extensible column.
The beneficial effects of the utility model are：
The utility model, can be free by telescopic column by the spacing of the freely adjustable two groups of lifts canopy support of push cylinder
The height of regulation lift canopy support, simple in construction, operation is flexible, overcomes traditional advance support and has that process efficiency is low, workman
The problems such as labor intensity is big, dangerous, back of constructing sinks soon, termination is difficult supporting, it is adaptable to generic working face
Face.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme in the utility model embodiment, it will make below to required in embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present utility model,
For those of ordinary skill in the art, without having to pay creative labor, it can also be obtained according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Marked in figure：
1- back timbers；2- bottom girders；3- footstocks；4- bases；5- telescopic columns；6- push cylinder；7- bearing pins.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.
As shown in figure 1, the fully-mechanized mining working automatic moving type of the present embodiment lifts canopy, including at least two groups pass through the phase of push cylinder 6
The lift canopy support connected, lift canopy support includes back timber 1, bottom girder 2, footstock 3, base 4 and telescopic column 5.
Footstock 3 is set on back timber 1, and base 4 is arranged on bottom girder 2, and the two ends of telescopic column 5 are connected by bearing pin 7 push up respectively
Seat 3 and base 4, footstock 3 and base 4 also act as the effect of transmission power.
The two ends of push cylinder 1 connect the base 4 of two groups of lift canopy supports respectively, for two groups of lift canopy supports of push-and-pull, so as to adjust
Save the distance of two groups of lift canopy supports.
Back timber 1 is the I-steel of 2600mm length, for carrying out supporting to working face upper end and advanced section top plate.
Bottom girder 2 is the I-steel of 2240mm length, for being supported to working face upper end top plate.
Telescopic column 5 is stroke 840mm ZF2200/16/24 type hydraulically extensible columns, can be according to lift canopy support conditions
Lift adjustment is carried out to back timber 1.
Working face upper end is replaced during canopy, it is necessary to when moving forward lift canopy support, one of which be lifted by telescopic column 5
The back timber 1 of canopy support departs from top plate, is then pushed ahead group lift canopy support by push cylinder 6, and again by flexible
Column 5 rises back timber 1, holds out against top plate.
Move forward another group of lift canopy support in the same manner, finally make two groups of lift canopy supports complete to working face upper end and
The supporting of advanced section top plate.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
